Title: V-groove setting method for spectacle lens
Inventor: KIKUCHI YOSHIHIRO
IPC: G01B21/32
Filed: 1992-08-07
Abstract: PURPOSE:To eliminate error by determining the amount of error between a preset eye point position and an eye point position on the front face of a lens for deformed spectacle frame shape and then correcting the position. CONSTITUTION:A main frame 201 in a factory 200 sets a V-groove in the edge of a spectacle lens based on a V-groove mode designated by a terminal computer 101 in a spectacle shop 100. The V-groove thus set is then transmitted to each terminal computer 204 where V-grooving is performed. In other words, the spectacle frame shape is deformed such that the Z-axis component of frame shape matches with the Z-axis component of the V-groove thus set while keeping constant the peripheral length of the spectacle frame. Pupil position, i.e., eye point position, on the front face of lens is then determined for deformed spectacle frame shape thus determining the error amount between the eye point position thus determined and a preset eye point position. Eye point position for deformed frame shape is then corrected based on the error amount thus determined. This method eliminates error of eye point position on a spectacle lens due to deformation of frame shape.

A dynamic vector is finally obtained from the relative address. When the calculating section 1 rewrites the content of a minimum value register MR, the relative address is stored in the 2nd address register AR2 and fetched as the dynamic vector.

Title: Active noise eliminating device
Inventor: MATSUURA TETSUYA
IPC: H03H17/06
Filed: 1992-08-07
Abstract: PURPOSE:To increase the reduction quantity of a noise by removing a reflected sound component from the detection signal of a microphone as to active noise elimination. CONSTITUTION:A detection microphone 5, a noise eliminating speaker 6, and a monitor microphone 7 are arranged in a duct 1. A signal detected by the detection microphone 5 and an error signal detected by the monitor microphone 7 are inputted to an adaptive FIR filter 10. The adaptive FIR filter 10 generates a reflected sound signal which is equal in amplitude to and opposite in phase from the noise in the duct 1 and outputs it to the sound eliminating speaker 6. A canceler 17 removes the reflected sound component included in the signal detected by the monitor microphone 7. Therefore, the reflected sound which is equal in amplitude to and opposite in phase from the noise generated by a noise source 2 is radiated from the noise eliminating speaker 6 and the reduction quantity of the noise becomes large.

Abstract: PURPOSE:To execute the program trace without decreasing remarkably a processing speed of a CPU by a buffer memory of a small capacity, by providing a tracer consisting of a buffer monitoring circuit, a buffer memory, and a trace memory. CONSTITUTION:When the execution of a microprogram is started, a tracer 3 starts simultaneously its operation, and a buffer memory 5 inputs an address and a data which are brought to access to a main memory 2 through a bus 100 by a CPU 1. Subsequently, they are outputted to a trace memory 6, but in case when the stagnation of the data of the memory 5 has exceeded a prescribed quantity, a buffer monitoring circuit 7 detects it, and outputs a microprogram inhibit signal 101. As a result, an AND circuit 10 inhibits an output of a ready signal 104 to the CPU 1, and the CPU 1 stops executing the program. Subsequently, when the stagnation of the data of the memory 5 decreases from the prescribed value, the circuit 7 stops outputting the signal 101, and the CPU 1 restarts to execute the program, therefore, the trace can be executed without decreasing remarkably the processing speed by a buffer memory of a small capacity.
